Yellow sapphires are far more valuable if they have not been treated by high temperature heating. The yellow sapphires that we offer for sale are all 100% untreated in every way. Yellow sapphires usually have “feather” type inclusions. These inclusions seen under magnification look very much like a bird’s feather. If a yellow sapphire has been heated at a high temperature these feathers are destroyed and are easily identifiable by a trained gemologist. It is very unusual for natural untreated yellow sapphires to not have any internal feathers, making them so easy to identify.

We only sell natural gemstones, mined from the earth. We do not deal in any synthetic or lab-created gems. We guarantee all our gems to be natural and as described.
